Rasmus Hojlund was seen by the media zone with an ice suit tied to his calf on Wednesday evening.
The Manchester United striker, who had scored the opening goal for Man United in their 4-1 victory for the season, smiled at reporters while he passed.
Hojlund did not seem to be bad and the peloton could only be for tightness or a precautionary measure, although the size of the injury is not yet known.
The Danish striker is perhaps more under the microscope than any other member of the Ruben Amorim team as he looks now.
After struggling last season in the team's diabolical campaign, Hojlund still has plenty to prove and United is on the market for a new frontman.
They made their step for Benjamin Sesko from RB Leipzig on Wednesday, as Chris Wheeler from Mail Sport reported.
But Hojlund was in any case able to offer his Food for Thought manager with a promising display in the latest Premier League Summer Series match.
He hit the post early in the game, but, fearlessly, he then led a look of the header along the keeper for the first goal of the match against the cherries at Solider Field, Chicago.
Hojlund believed that he had a third with a touch of Amad Diallo's shot, but eventually had to settle for one.
United had limited their top striker goals to Ollie Watkins and Sesko, but now the Slovenian powerhouse is the first choice.
It is understood that the German club has a men's agreement with the 22-year-old to let him go for £ 60-70 million plus add-ons to certain clubs.
United has been following Sesko for some time and director of Christopher Vivell has been a key figure in negotiations that have previously worked at Leipzig and the former Club Red Bull Salzburg of the player.
Sesko has scored 39 goals in 87 games for Leipzig and 16 goals in 41 performances for Slovenia.
United had originally hoped to sign Liam Delap this summer, but the striker of Ipswich moved to Chelsea instead.
A number of other strikers have been considered, but Nicolas Jackson from Isak and Chelsea were considered too expensive.
